    Abstract: The disclosure relates to a process for making phosphorus pentoxide by subjecting elemental yellow phosphorus to combustion with dried air inside a steel-made combustion chamber with utilization of the reaction heat for the production of energy. To this end, the disclosure provides for the combustion to be effected inside a combustion chamber of which the walls are arranged so as to form a cooling system with cavities therein; for water or a water/steam-mixture as a heat carrier abstracting the reaction heat to be circulated through the cooling system, the water or water/steam-mixture assuming an increased temperature being circulated, preferably under increased pressure; for steam formed in the cooling system to be continuously taken therefrom; for an equivalent proportion of fresh desalted water to be introduced into the cooling system; for hot gaseous phosphorus pentoxide issuing from the combustion chamber to be condensed or worked up into phosphoric acid; for the steam taken from the cooling system to be passed through a steam delivery pipe disposed in the upper portion of the combustion chamber, or through a delivery conduit for product gas containing phosphorus pentoxide; for the steam to be heated therein to a temperature of 400 DEG to 600 DEG C. under constant pressure, and for the steam so superheated to be used.

    Abstract: STABILIZED AND DESENSITIZED FLOWABLE RED PHOSPHORUS Stabilized and desensitized pulverulent flowable red phosphorus consisting of particles with a size of at most 2 mm, and process for making it. To this end, red phosphorus is prepared from yellow phosphorus. Next, an aqueous suspension of pulverulent red phosphorus is freed from residual fractions of yellow phosphorus by treating it with a sodium hydroxide solution, and the red phosphorus in the aqueous suspension is stabilized with aluminum hydroxide and a hardened epoxide resin and desensitized in the aqueous suspension by means of a water-emulsifiable organic compound which is liquid, inactive with respect to phosphorus and has a low vapor pressure at room temperature and at atmospheric pressure.
